Solution

I can write the editorial, but the full requested format is much longer than a single response can fit while still keeping the explanation and code complete. I’ll split it into two parts: the first message will contain the editorial through the algorithm and proof, and the second message will contain the Python solution, walkthrough, tests, and edge cases.
